Pottermore's ebook store launched today, offering up English-language version of all the novels. Editions in French, Italian, German and Spanish will feature in a second wave.

The site claims the ebooks work with all dedicated e-readers, tablets and mobile phones. The first three novels—the shortest ones—are priced at $8 each, while the final four, which are much longer, go for $10. Or, you can by the entire back catalog for $58. If you're a crazy fan.

All of which is great, if rather insane. There cannot be any other publication or franchise on the planet that could get away with a dedicated system like this to sell just seven books. About childhood wizards. Well done, J.K. [Pottermore via Wall Street Journal]
